TRACTOR Y WHEEL.

Application ied April s,

To all 'ic-7mm t may concern; f

Be it known that I, THOMAS C. WHITE- HEAD, a citizen of the UnitedStates of Americaj residing at Detroit, in the county of Wayne and Stateof Michigan, havey iiivented certain new and useful Improvements s inrllractor I'Vheels, of which the following is aspeciication, referencebeing had therein to the accompanying drawings. y

The invention relates to tractor wheels and the present applicationforms in vrpart a division of the subject-matter of my application,Serial No. 446,910, iiled February 2l, 1921. It is the primary object ofthe invention to obtain a tractor wheel, ithe traction of which may bevaried to correspond to the load which is pulled.V It is a furtherobject to adapt the wheel'for various con-` ditions of service ashereinafter set forth.

In the drawings:

Figure l is a side elevation showing one- Klialf of the tractor wheel;and

Figure 2 is a cross-section thereof. y VIn the use of tractors for thepulling of loads, it frequently happens that the weightr carried by thetractor wheel is insuiicient to secure the required traction. While thisdiiiiculty might be overcome by loading the forme-d ot cast metalV andtegral hub D. At one or morepoints in thek sides of thedisk are arrangedopenings E which may be closed by a pair of oppositely arranged disheddisks F with a clamping bolt G for expanding the saine. Any othersuitable closure may, however,
